服务器经常有多个网卡,为了保证网络冗余性,一个网卡出现故障时,不导致网络服务中断,可以懂多网卡网卡绑定来解决此问题。
环境:
系统:Ubuntu16.04 网卡:em1 em2 ip:192.168.0.46
安装ifenslave:
sudo apt-get install ifenslave echo "bonding" >>/etc/modules
网卡绑定配置:
vim /etc/network/interfaces
auto bond0 iface bond0 inet static address 192.168.0.46 netmask 255.255.255.0 bond-slaves none bond-mode active-backup bond-miimon 100 auto eno1 iface eno1 inet manual bond-master bond0 bond-primary eno1 eno2 auto eno2 iface eno2 inet manual bond-master bond0 bond-primary eno1 eno2
配置完成后重启网卡(如果重启不生效,请重启服务器):
/etc/init.d/networking restart
ifconfig 查看配置是否生效:
